When electric lighting was a new idea, it was compared unfavourably to gas lighting. Some felt that such bright lighting was unhealthy in various ways.
In particular, one theory held that electric light would mimic daylight and thereby "wear out the eyes or brain more quickly" And remember that was with 16 candle power carbon filament lamps that give a dim and yellow light by todays standards.

Electric light was generally accepted to be safer than gas, though this took a while !
Gas carried risks of CO poisoning and explosions, oil lamps and candles were a fire risk.

"Whilst it is true that gas lighting is now being challenged by our competitors, it is the duty of everyone in the gas industry to ensure that gas lighting remains in use, and that gas is given due consideration for new housing schemes. Every gas light lost is an electric light gained, and every extra electric light is a chance for our competitors to sell electricity at inflated prices for lighting, and thereby subsidise electricity sold for heating and cooking, which as we all know are done better and cheaper by gas.
Only gas is sold at the same low, affordable price, to anyone to use for any purpose."

From a gas industry text book issued just before WW2 ! the gas industry fought long and hard. But reluctantly admitted defeat over lighting.

Yes, Wunsch has done some work on health effects of incandescent lighting and recommends low voltage d.c. halogen bulbs run so the red end of the spectrum is dominant. There have not been any cases of CO poisoning as far as I know caused by using incandescent bulbs.
